This episode of What the Heck is in my Garden? is focused on the unexpectedly rich use and history of the Marigold (Tagetes genus). All the way from Mexican Day of the Dead celebrations, repelling garden pests, helping in the fight against age-related macular degeneration to Aztec psychoactive trances, the marigold has an intriguing history hidden beneath its bright colours.

All this and more will be discussed on episode 3 on the What the Heck is in my Garden? podcast; Marigold!
